-Speed control -Position control Using “Soft-start”
This function is effective for all of the accel./decel. operation in speed control and position control (except for pulse train input).
The time setting is for the speed range of 0 to 2000 [r/min].
Acceleration time 2 and deceleration time 2 are effective while ACC0 signal is on.
ON/OFF input of ACC0 is always effective and accel. time/decel. time can also be changed over. The ACC0 is a signal allocated to CONTrol
of system parameters.
Acceleration time 1 and deceleration 1 can be set separately. For example, only deceleration time can be lengthened. Most suitable
deceleration time can be selected depending on the load volume in driving a carrier machine.
Set the accel. and decel. time at 0.000s to send the analog speed reference voltage signal from the host controller and to feedback the freq.
dividing output from the amplifier.
Non-linear (S-curve) filter coefficient can be set for pulse train input in position control. See 6.1.5.
Torque control voltage can be changed by a filter time constant concerning torque command voltage. See 5.6 Torque control.
6.1.4 Soft OT
The soft OT (overtravel preventive signal set by software) can be set.
